2. Description of Related Art
As optical and semiconductor manufacturing technology advances, Liquid Crystal Display (hereafter LCD) is widely used in all kinds of electronic appliances. LCD has several advantages, such as high resolution, small volume, light weight, low driving voltage, low power consumption and broad application. Thus, LCD application has become popular in portable TVs, cellular phones, camcorders, notebook personal computers (PCs), desktop PCs, projectors and other consumer electronics or computer products. LCD has become a mainstream technology in the display market.
Generally speaking, an LCD is secured to an upper cover of a notebook PC. The upper cover can be opened while turning on the notebook PC. An LCD is exposed after opening the upper cover. The upper cover is connected pivotally to a mainframe of the notebook PC. Therefore, The LCD can be adjusted to a desired position by rotating the upper cover in relation to the mainframe.
Because a notebook PC is portable, a user often carries it out of the office to a desired place. In different circumstances, the notebook PC is used for demonstration purposes. However, traditionally, the LCD of notebook PC doesn't have an ability to display information in as large viewing angle as to all of the people around it. Thus, a new model PC entitled Tablet Personal Computer has been introduced to the market. A tablet PC has a 180-degree rotatable LCD panel. A Tablet Personal Computer (hereafter tablet PC) providing both keyboard input and manual input not only changes computer use habits but also creates a milestone for information technology. Moreover, the tablet PC operation systems can provide a manual input function. The tablet PC has accordingly a user-friendly manual input interface and a 180-degree rotatable LCD panel. Therefore, persons around the tablet PC can easily read the information displayed on the LCD by rotating the LCD panel.
The LCD panel's two degrees of rotation function may cause the LCD panel to shake or give rise to other unsteady circumstances. Therefore, a means for angular fixing of the LCD panel after moving the same to a desired position is essential. For the forgoing reasons, there is a need for providing a steady input and display environment.
It is therefore an objective of the present invention to provide a swivel hinge apparatus with an angular fixing function in order to provide a steady input and display environment.
In accordance with the foregoing and other objectives of the present invention, a swivel hinge with angular fixing structure is employed to connect a mainframe and a display means of a notebook computer. The swivel hinge includes a fixture part, a fixture friction ring, a rotation part, a rotation friction ring, and an elastic ring. The fixture part mounted on the mainframe has a through hole in the center thereof. The fixture friction ring fixed on the fixture part has at least one holder on the surface. The rotation friction ring fixed on the rotation part has at least one slot in the surface thereof. The elastic ring is located between the fixture part and the fixture friction ring. If the slot and the holder on the friction ring fit into each other, the desired angular fixing function is provided.
According to one preferred embodiment of present invention, the rotation part includes a rotation plate and a rotation base. The rotation plate connects to the rotation base via the through hole of the fixture part. That is, the fixture part is placed between the rotation plate and the rotation base.
According to one preferred embodiment of present invention, the fixture friction ring alternatively has at least one slot, and the rotation friction ring alternatively has at least one holder. If the holder and the slot fit each other, the desired angular fixing function is provided. The elastic ring can be disposed between the rotation friction ring and the rotation part, or be disposed between the fixture friction ring and the fixture part. But the elastic ring cannot be disposed between the fixture friction ring and the rotation friction ring.
In conclusion, the swivel hinge apparatus of present can provide not only a multi-angle fixing function but also a steady input and display environment for users.
It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the invention as claimed.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. In the drawings,
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

Referring
The Z-axis hinge's angular fixing function is conducted by fitting position elements (15 and 15a, 19 and 19a) respectively on the fixture friction ring and the rotation friction ring together. Referring
In addition, in order to provide desired angular fixing positions on the circular friction ring, the position element can be made in specific positions. For example, the position elements can be made at 0 degrees, 90 degrees, and 180 degrees of the circular friction ring, resulting in an angular fixing function of 0 degrees, 90 degrees, and 180 s provided around the Z axis.
In one preferred embodiment of present invention, an elastic ring can be added in a swivel hinge apparatus to provide steady angular fixing function. For example (referring to FIG. 2), an elastic ring 24 is disposed between the rotation friction ring 18 and the rotation base 26. Referring
Referring to
For example (referring FIG. 2), pin holders 23 are respectively installed on two sides of the fixture part 22 and corresponding pins 9 are under the rotation plate 11. The pin holders 23 are employed to block the range of motion of the pins 9 such that the rotation plate 11 rotates within a predetermined rotation direction and range. In one preferred embodiment of present invention, the swivel hinge apparatus can provide a rotation range of 180 degrees around the Z-axis.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
